DRY OPTERID ACE AE
Dryopteris intermedia (Muhl. ex Willd.) A. Gray
Chromosome voucher: 2n=82 (sexual diploid). Count by M.D.Windham, May 1 2012. Otherwise, I (CJR)
thought that this might be D. xtriploidea, based on the basal basiscopic pinnules (which would bring it to
carthusiana?) and the glandularity (which would bring it to intermedia).
